Austin Reed Sigg arrested in connection to the Jessica Ridgeway case in Westminster

WESTMINSTER, Colo. (KUSA)- Westminster Police have made an arrest in the Jessica Ridgeway case. The suspect, 17-year-old Austin Reed Sigg, was taken into custody on Tuesday. Sigg is a student at Arapahoe Community College, according to the custody report released by Westminster Police.

9NEWS Investigative Reporter Jeremy Jojola was able to speak with Sigg's mother, but she did not want to comment on his arrest.

Westminster Police said in a press release Wednesday: "Late Tuesday evening, police received a call that led them to a home near the Ketner Lake Open Space. With this discovery, police [announce] they made an arrest in the Ridgeway murder investigation. Additionally, authorities will file charges against the attacker in the May 28, 2012 attempted abduction at Ketner Lake."

Police will release additional information in a press conference at noon. The police tip line is still operating: 303-658-4336 or email: PDamberalert@cityofwestminster.us.

Westminster Police announced on Monday evening there is a direct link between the Memorial Day attempted abduction at Ketner Lake and the Jessica Ridgeway murder case.

Westminster Investigator Trevor Materasso would not say if investigators believe the same person was involved in both attacks.

"We're limited beyond that to talk in detail or give specifics on how those two connections are made," Investigator Trevor Materasso told 9NEWS.

Over the Memorial Day weekend police say a jogger was attacked from behind at Ketner Lake by a man who used a chemical-soaked rag to try and subdue her. The woman fought off her would-be abductor. For days, police spoke of a possible connection between the Ketner Lake incident and the Jessica Ridgeway kidnapping, but it wasn't until Monday that they officially linked the two cases.

Monday evening, police also told 9NEWS that they have ruled out other evidence that has been recovered as they investigate the Ridgeway case. Most notably, police say some grocery receipts for garbage bags that were discovered after Ridgeway's body was found are not related to the case.

Meanwhile, investigators are still testing potential evidence that was found by a woman at Pattridge Park on Sunday. The woman reported to police that she found a "clump of hair" while walking in a field. Police collected that item and say they are not certain it is hair and are waiting for further testing to determine if it's relevant to the Ridgeway investigation.

Thousands of tips have been received in the Ridgeway case and police are still asking for the public's help.
